Anemone dieing? Maybe you can help

[Mikey Mane The Flare]

Been like this for almost 24 hours but all my corals are fine. Did a water change yesterday morning 10g in a 55g. Anemone deflated. Then later after dinner I used some ph buffer as it was 7.6. Maybe I don't have enough flow? No power head.

No powerhead in a 55?

Also do not use buffers, you have other issues, I cannot link them now but a quick search of this forum will lead you in the right direction.

Long story short, you probably to much CO2 in your house, you should add a CO2 scrubber to your skimmer, or get some fresh air to it.

What are your other corals? Easy softies and some LPS, or some harder LPS and SPS?
